Perhaps the evening’s most unusual entry was Yoko Ono’s "To Match the Sky," a "birthday performance piece" written in Riley’s honor. It consisted of four lines of text, with instructions to improvise sounds. Beginning with "Sky with clouds floating," Kronos keened and plucked. Rain and snow followed; on the fourth line, "Thunder and lightening" (sic), Harrington asked the audience to contribute storm-appropriate noise. The crowd responded with gusto. Riley, seated a few rows from the stage, pounded along gleefully.
